Abnormal strong burn-in degradation of highly efficient polymer solar cells caused by spinodal donor-acceptor demixing Open
The performance of organic solar cells is determined by the delicate, meticulously optimized bulk-heterojunction microstructure, which consists of finely mixed and relatively separated donor/acceptor regions. Here we demonstrate an abnorma…

Reverse-Voltage Bias Induced Shunt Formation in Cu(In,Ga)Se2 Thin Film Solar Cells: an Approach with Three-Dimensional Electro-Thermal Simulations Open
By partial shading of thin-film solar panels a high reverse voltage drops across shaded solar cells. These solar cells may be driven into breakdown, which causes in the worst case severe damage to the cell. With dark lock-in thermography t…
